Testing the number of web browser instances

Question

Testing the number of web browser instances

Whenever I execute my tests using TestNG, multiple browser instances are launched before the tests begin.

This is how my testng.xml file looks:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE suite SYSTEM "http://testng.org/testng-1.0.dtd">
<suite name="Suite">
    <test name="Test">
        <classes>
            <class name="tst.TST4"/>
            <class name="tst.TST3"/>
            <class name="tst.TST2"/>
        </classes>
    </test>
    <!-- Test -->
</suite>
<!-- Suite -->

I have a large number of tests to run, so I am concerned whether it's normal for TestNG to open a new instance of the browser for each individual test out of 1000 before starting the testing process?

It is beneficial to create a setUp() and tearDown() method in your test script to optimize resource usage when dealing with a large number of tests. In these methods, you can prepare the necessary data before each test and clean up afterwards.

Here's an example:

import unittest
from selenium import webdriver

class SearchText(unittest.TestCase):
    def setUp(self):
        # create a new Firefox session
        self.driver = webdriver.Firefox()
        self.driver.implicitly_wait(30)
        self.driver.maximize_window()
        # navigate to the application home page
        self.driver.get("http://www.google.com/")

    def tearDown(self):
        # close the browser window
        self.driver.quit()
